Scout report
Um Won-Sang is a 27-year-old attacking midfielder at Ulsan Hyundai FC, rated 35.2 overall by Field Insider's model, ranking 40th of 148 on scout potential in the K League 1. In his prime years, he has been a fringe squad member this season (17.9% of available minutes). He brings 0.59 goal contributions per 90 (0.15 goals, 0.44 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Won-Sang.
Judged on this season alone, Won-Sang graded 10 — a workmanlike campaign that ranks 5th of 7 of the 7 attacking midfielders in the K League 1, on 1 goal and 3 assists in 30 appearances (0.589 involvements per 90).
Year-on-year, that's a drop on last season (Season 15 → 10). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 35, 4th of 7 of the 7 attacking midfielders in the K League 1. At 27 Won-Sang is in his prime years, and a market index of 8.6 reflects that trajectory.
Below his 2022/23 peak but holding a solid level — the platform for a return is there.
Output in context · Ulsan Hyundai FC finished 3rd of 6 · a mid-table side

Strengths
- Final-third output. 0.59 goal contributions per 90 (0.15 goals, 0.44 assists) — productive for the role.
Watch points
- Game time. Only 17.9% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 35.2, Won-Sang carries the 4th-highest potential of the attacking midfielders in the K League 1 of 7 — though on just 30 appearances this season, so the standing rests on a small sample. In the final third he profiles as a genuine goal threat (0.59 goal contributions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
